Comments from our clients


Ports of Jersey retained Stephen to provide guidance and support to our regulatory programmes.  His insight, wisdom and regulatory knowledge has been invaluable to Ports of Jersey in developing our regulatory framework.

Doug Bannister, CEO, Ports of Jersey

Stephen analysed from a consumer perspective complex financial information in relation to a recent price control appeal to the CMA. Stephen’s report was an integral part of The Consumer Council submission to the CMA. Stephen was knowledgeable, courteous and efficient beyond reproach

Paulino Garcia, Senior Policy Officer, Consumer Council Northern Ireland

Stephen’s insight into the UK regulatory landscape is unparalleled and extremely valuable for investors and others concerned with such matters

Abe Cary, Westchester Capital Management

Stephen provided expert advice to the ORR on a number of projects as part of the structure of charges review, under the 2018 periodic review of Network Rail (PR18). Stephen’s input included providing useful challenge and feedback on a complex impact assessment of charging options, which enabled us to improve the robustness of the assessment. Across the projects he worked on, Stephen demonstrated a good understanding of the relevant regulatory issues and of the relevant rail industry context. Stephen was also very easy to work with, and flexible in terms of his input (i.e. when and how he provided it).

Alexanda Bobocica, Senior Economist, ORR

I think Stephen is really good:

  • Deeply knowledgeable
  • Easy to work with
  • Strikes a good balance between theoretical purity and hard delivery pragmatics
  • Strikes a good balance between understanding company positions and understanding regulator position
  • Passionate/dedicated

We asked Stephen to prepare a report to assist us with understanding the best way to approach a complicated issue in the fields of competition and regulation. Stephen worked quickly and produced a well-written document which set out clearly and concisely key theoretical and analytical considerations, as well as the way similar issues had been approached in a number of different industry sectors. The report was helpful in assisting us with tackling this difficult issue.

“Stephen was commissioned by the CAA to review and quality assure its market power assessments of Heathrow, Gatwick and Stansted. Stephen’s input was very valuable, combining his sound understanding of competition economics and his experience gained in other sectors in helpful and practical advice. The CAA’s work benefited greatly from Stephen’s involvement.”

John Templeton, Interim Head of Competition Assessment, CAA

“Stephen prepared a critique for The Scotch Whisky Association of the Scottish Government’s Regulatory Impact Assessment supporting their legislation introducing minimum pricing of alcohol. The report was detailed but balanced, and identified a number of failings in the Scottish Government’s methodology and conclusions reached in the RIA. We found this an extremely useful support to our legal challenge and would certainly use SLG Economics again and recommend them to other potential clients”

Glen Barclay, Director Legal Affairs, The Scotch Whiskey Association

“Stephen has provided regular lectures each year on our undergraduate and postgraduate level courses in microeconomics. Our students find these lectures to be very engaging, analytically sound and displaying great understanding of the academic and professional literature. They were, to put it simply, wonderful. There is no doubt at all that Stephen is a talented and enthusiastic economist, with a gift for explaining complex ideas in an elegant fashion”
